ya good call man . even though the two manifolds draw from a common source(the intercooler) we are still going to have a balance tube to ensure even cylinder filling . different length pipes and bends etc. im sure its going to be tricky to tune regardless , mostly due to the dual throttle bodies . gettin the tip in dialed should be a good time .

I guess it might not be super bad, if you can at least monitor each side separately with dual 02 sensors, you may find that all you need to do is offset one side by 1% or something, at least hopefully it is that easy...haha. Good luck!
